[PATCH] D68050: WIP Make attribute target work better with AArch64

[Alexandros Lamprineas via Phabricator via llvm-commits]

labrinea added a comment.

> ARM and AArch64 have a way to list the implied target features using the TargetParser but we can't directly use that in CodeGenModule because it's tied to the backend.

It seems that `initFeatureMap` allows this, but it's currently limited to inferring features from the CPU name. The ARMTargetInfo class provides an override of this function. I think for this patch to work we would need an override for AArch64 with the ability to handle Arch names.
